Thg1l Gene Summary [Rat]
Predicted to enable several functions, including guanyl-nucleotide exchange factor activity; magnesium ion binding activity; and purine ribonucleoside triphosphate binding activity. Predicted to be involved in several processes, including protein homotetramerization; stress-induced mitochondrial fusion; and tRNA modification. Predicted to be located in mitochondrion. Predicted to be part of transferase complex. Human ortholog(s) of this gene implicated in autosomal recessive spinocerebellar ataxia 28. Orthologous to human THG1L (tRNA-histidine guanylyltransferase 1 like). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Thg1l often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
